Bullying Others? Legalist Fanatics Turn on the Recorder

The protagonist is in an environment full of hidden rules. With absolute rational memory, extreme professional rules (laws/standards, etc.) And hard-core physical measurement tools, he carries out an aboveboard and irrefutable dimension reduction attack on perpetrators and corruptors. Instead of playing tricks, he only uses "absolutely compliant" plots to drive the villain to a dead end, and single-handedly crushes the entire "unspoken rule" system with "explicit rules".
